MCP16312-E/MS

The MCP16312-E/MS is a compact high-efficiency fixed frequency synchronous step-down DC-DC Converter operates from input voltage sources up to 30V. Integrated features include a high-side and a low-side switch, fixed frequency peak current mode control, internal compensation, peak current limit and over-temperature protection. The MCP16312 provides all the active functions for local DC-DC conversion, with fast transient response and accurate regulation. High converter efficiency is achieved by integrating the current-limited, low-resistance, high-speed high-side and low-side switches and associated drive circuitry. The MCP16311 is capable of running in PWM/PFM mode. It switches in PFM mode for light load conditions and for large buck conversion ratios. This results in a higher efficiency over all load ranges. The MCP16312 runs in PWM-only mode and is recommended for noise-sensitive applications.
